A double blind randomized controlled trial comparing primary suture closure with mesh augmented closure to reduce incisional hernia incidence

Background: Incisional hernia is the most frequently seen long term complication after laparotomy causing much morbidity and even mortality. The overall incidence remains 11-20%, despite studies attempting to optimize closing techniques. Two patient groups, patients with abdominal aortic aneurysm and obese patients, have a risk for incisional hernia after laparotomy of more than 30%. These patients might benefit from mesh augmented midline closure as a means to reduce incisional hernia incidence. Methods/design. The PRImary Mesh Closure of Abdominal Midline Wound (PRIMA) trial is a double-blinded international multicenter randomized controlled trial comparing running slowly absorbable suture closure with the same closure augmented with a sublay or onlay mesh. Primary endpoint will be incisional hernia incidence 2 years postoperatively. Secondary outcomes will be postoperative complications, pain, quality of life and cost effectiveness.A total of 460 patients will be included in three arms of the study and randomized between running suture closure, onlay mesh closure or sublay mesh closure. Follow-up will be at 1, 3, 12 and 24 months with ultrasound imaging performed at 6 and 24 months to objectify the presence of incisional hernia. Patients, investigators and radiologists will be blinded throughout the whole follow up. Disccusion. The use of prosthetic mesh has proven effective and safe in incisional hernia surgery however its use in a prophylactic manner has yet to be properly investigated. The PRIMA trial will provide level 1b evidence whether mesh augmented midline abdominal closure reduces incisional hernia incidence in high risk groups. Trial registration.

Investigation of the usability of industrial mining wastes in agriculture

In this study, the usability of the mixtures consisting of lignite coal taken from Tekirdag region and marble and travertine wastes taken from the marble factory in Gumushane region in local bean (Kelkit) cultivation was researched. First, control samples were created using only humus soil without coal, marble, or travertine dust. Then, for each coal or coal waste, coal/coal waste—waste marble dust and coal/coal waste—travertine dust mixtures were formed. These mixtures were obtained by mixing 25%, 50%, 75%, and 100% by weight of coal and 25%, 50%, and 75% by weight of marble and travertine dust. Afterwards, local beans were planted in these mixtures and their development was followed under laboratory conditions. Additionally, temperature and humidity values were recorded at certain intervals, pH and heavy metal analysis measurements were made on the mixtures before and after bean planting, the height and leaf measurement of the beans grown and the number of beans grown in these beans were also followed, and chlorophyll analysis was performed on the bean plants grown in these mixtures. As a result, 50% Coal-3D + 50% Travertine mixture had the maximum length increase, that 25% Coal Waste (Powder)-K3 + 75% Marble mixture had the highest number of beans, and that 50% Coal Waste -AK + 50% Marble mixture had the maximum leaf formation. In these mixtures, maximum 12 beans were grown and maximum 93 leaves were formed. Also, the bean plant was grown in all mixtures. The chlorophyll contents were at least as much as the values of the beans grown only in soil. However, heavy metal values do not exceed the permissible limit values in soil

Stakeholders’ Perspectives on Utilization of Logging Residues for Bioenergy in Turkey

Although using logging residues for bioenergy is not a new issue for countries such as Sweden, Finland, Austria, Germany, etc. that are developed in terms of forestry, it is a new issue that requires studying for countries such as Turkey. This study investigates the views of forest engineers working in forest enterprises, researchers working in forestry research institutes and academicians working at universities concerning the use of logging residues for bioenergy that are not currently used in energy production. Within the framework of the study, a questionnaire was sent out to 181 forest engineers, 77 academic staff members and 29 research institute employees, a total of 287 respondents. According to the results of the study, logging residues that are either left in the forest floor or collected by forest villagers for the purpose of fire wood have a favorable potential for energy and forestry if they are used in bioenergy production. Thus, the issue is substantial and of primary importance for Turkey. On the other hand, there are barriers in developing bioenergy sector and using logging residues for this purpose. In order to remove these barriers, first of all, forestry administration should clarify its strategies and policies related to the issue

Advanced glycation end products as a biomarker for incisional hernia

Background: Incisional hernia is one of the most frequent complications after abdominal surgery, with incidences up to 30%. A reliable biomarker for the prediction of this complication is lacking. Advanced glycosylation end products (AGEs), also known as non-enzymatic collagen crosslinks, are correlated with aging, smoking, hyperglycemia, hyperlipidemia and oxidative stress. In this study the accumulation of AGEs and the relation between AGEs and incisional hernia were investigated. Materials and methods: In an explorato

Functional outcome after laparoscopic and open incisional hernia repair

Abstract: Background: The debate about the advantages of laparoscopic versus open incisional hernia repair is still ongoing. The primary outcomes of already published studies are mainly recurrence, pain and quality of life. Data on postoperative abdominal wall function after these corrections is still lacking. In this single center study muscle strength and transverse abdominal muscle thickness were analysed with regard to open and laparoscopic techniques. Methods: Thirty-five patients that underwent open and laparoscopic midline incisional hernia correction were included. Approximation of the rectus muscles was included in some open procedures but never in laparoscopic correction. Twelve healthy subjects without any abdominal operation functioned as a control group. Trunk flexion muscle strength of all operated patients and 12 healthy subjects was studied with the Biodex® isokinetic dynamometer and conventional abdominal muscle trainers for the rectus and oblique abdominal muscles. All patients underwent ultrasound examination of the abdominal wall for analysing transverse abdominal muscle thickness. Results: The mean torque/weight (%) for trunk flexion, measured with the Biodex®, was significantly higher in the control compared with the total patient group. Comparing trunk flexion with the Biodex® after either laparoscopic or open incisional hernia repair showed a trend in favour of the open group after adjusting for gender. The muscle strength measured by the conventional abdominal muscle trainers showed no differences between the operation groups. The transverse abdominal muscle thickness difference between rest and contraction was significantly higher in the open repair group. Conclusions: The isokinetic strength of trunk flexor muscles is reduced after an operation for incisional hernia. There is some evidence that open repair with approximation of the rectus abdominis muscles results in higher muscle strength of the rectus muscles and higher thickness differences between res

Erol Güngör'ün Düşüncesinde Felsefe Bilim Faaliyeti Olarak Sosyal Psikoloji

It is not necessary to explain the scientific thoughts of Erol Güngör as a social psychologist who conducted research in this area solely, because his opinion about science extended the kind of studies. He has an exact aim with his worldview that constructs his scientific thought that includes solving his own public problems and setting ways to convert the problems into activity which is called problem-solving. Thus, his thought is that develop a worldview and study for scientific research. The position includes that sci ence and philosophy are together opening new discussions about rethinking the topic of psychology. In his view, the topic of social psychology is about public issues that are bonded to own public intrinsically. In this point, the conclusion is that a social psychologist should be both a scientist and a philosopher. It means being “münevver” in his vocabulary. Otherwise, it will be incomplete for problem-solving because of studying for research with only methodological purposes. That's why his claim is important because of constructing a new path about science within Turkish and Islamic thoughts. In this study, the main claim is that when Güngör’s thoughts are evaluated with the philosophical science and the existence of the social-culture dimension, his cases converted to scientific problems within social psychology and argued to solving within the problem-solving activity

Abdominal Wall Hernia: new perspectives for clinical research

__Abstract__ Abdominal wall surgery is a broad term, covering different treatment strategies for all different types of abdominal wall hernias. For example, an inguinal hernia is a totally different entity than an incisional hernia and requires a different treatment strategy. Nevertheless, some issue
